Abstract
Infrared spectroscopy was applied for the investigation of the combined effects of γ-irradiation and heat on poly (vinyl alcohol)(PVA). The samples were exposed in an atmosphere of air at room temperature to doses ranging from 0.5 to 15 Mrads. The obtained results revealed that exposure to γ-radiation produces no considerable changes in the IR spectra of PVA apart from very slight changes in the intensities of the absorption bands. The crystallinity of the irradiated samples was determined by following the induced changes in the absorbances of the crystalline bands.
